Chapter 29: Problem 20

_____ muscles are also called voluntary muscles. a. Cardiac b. Smooth c. Striated d. Skeletal

Short Answer

Expert verified
Skeletal

Step by step solution

01

Identify the Types of Muscles

Understand that the human body has three types of muscles: cardiac, smooth, and skeletal. Cardiac muscles are found in the heart, smooth muscles are found in organs like the stomach, and skeletal muscles are attached to bones and help with movement.
02

Define Voluntary Muscles

Voluntary muscles are muscles that can be consciously controlled by an individual. This means that a person can decide when to move them.
03

Match Muscle Types with Control

Review which muscles are controlled consciously. Cardiac muscles work involuntarily to pump blood. Smooth muscles also work involuntarily in processes like digestion. Skeletal muscles are controlled voluntarily to cause movement.
04

Choose the Correct Answer

Given that skeletal muscles are voluntary, the correct option in the list provided is Skeletal (d).

Key Concepts

These are the key concepts you need to understand to accurately answer the question.

Muscle Types
The human body has three main types of muscles, each with unique functions and characteristics. The first type is cardiac muscles. Found only in the heart, these muscles work involuntarily to pump blood throughout the body.
Next, we have smooth muscles. These are also involuntary and are found in organs like the stomach and intestines, where they help with processes like digestion.
Lastly, we have skeletal muscles. These are voluntary muscles, meaning we can control them consciously. They attach to bones and are responsible for all our movements, from walking to lifting objects.
Skeletal Muscles
Skeletal muscles are essential for movement and are the only type of voluntary muscle. They are connected to bones by tendons and work in pairs to help the body move.
When you decide to move, your brain sends a signal to these muscles to contract. This interaction between the brain and muscles allows for precise and controlled movements.
Additionally, skeletal muscles play a vital role in maintaining posture and generating heat through muscle contractions, which helps keep our body warm.
Human Anatomy
Understanding muscle types is crucial to understanding human anatomy. Muscles work together with bones and other structures to facilitate movement and maintain bodily functions.
In the skeletal system, bones provide the framework, and muscles enable movement by contracting and relaxing.
The complex coordination between different muscle types and other body systems illustrates the intricate design of human anatomy.
Recognizing the differences between voluntary and involuntary muscles helps us appreciate how our body performs a wide range of activities, both consciously and subconsciously.

How would muscle contractions be affected if ATP was completely depleted in a muscle fiber? a. Myosin heads will detach rapidly from the actinbinding sites, resulting in muscle relaxation. In a live person this causes rigor mortis, while in a recently dead person it results in "writer鈥檚 cramp". b. Myosin heads will not detach from the actinbinding sites, resulting in muscle stiffness. In a live person this causes rigor mortis, while in a recently dead person it results in "writer鈥檚 cramp". c. Myosin heads will detach rapidly from the actinbinding sites, resulting in muscle relaxation. In a live person this causes "writer鈥檚 cramp", while in a recently dead person it results in rigor mortis. d. Myosin heads will not detach from the actinbinding sites, resulting in muscle stiffness. In a live person this causes "writer鈥檚 cramp", while in a recently dead person it results in rigor mortis.
